n Auto Paper SelectionThe width is detected by the position of the tractor set to the width of continuous paper. The length in
feeding direction is detected by the number of holes per page entered on the copiers control panel. Bothdimensions are used to identify the size of the original, thereby enabling automatic selection of copy paper.
If width of original/lengthwise dimension > 1, A4 (LTR) is selected.If width of original/lengthwise dimension < 1, A4R (LTRR) is selected.
n Auto Paper SelectionStudy the table below for samples of identification:
n Feeding OriginalsWhen the Copy Start key is pressed, the first six pages are fed at longer intervals than usual, allowing
the user to fold the continuous paper into pages. Thereafter, the pages are fed continuously up to the lastpage.
n Delivered CopiesIf 250 or more copies are to be made, copying operation will stop at the 250th copy and the copier will
indicate a message asking the user to remove the copies from the copiers copy tray or the sorters non-sort bin. Copying operation will resume at a press on the Copy Start key.

B. Latent Image Formation BlockThis block consists of three steps at the end of
which positive charges are left in the areas of thedrum corresponding to the black areas of the orig-inal by removing the positive charges from thoseareas corresponding to the white areas of theoriginal.
The NP6085 uses an automatic surface poten-tial control mechanism to ensure a specific poten-tial for the dark and light areas of static images.

The surface of the drum is evenly charged topositive potential by the primary charging assem-bly to ensure primary potential.
The surface potential of the charged drum isdetermined by the potential of the grid; therefore,the grid is grounded through a varistor to ensurea specific surface potential.
E. Image Exposure (step 3)
Figure 2-107
The optical image of an original is projectedonto the surface of the drum, thereby neutralizingthe charges in the light areas.

F. Development (step 4)
Figure 2-108
As shown in Figure 2-108, the developingassembly consists of a developing cylinder com-posed of a fixed magnet and a cylinder thatrotates it and a magnetic blade.
The single-component developer used for theNP6085 consists of magnetite and resins. Thetoner (developer) has insulating characteristicsand becomes negatively charged by frictionagainst the rotating cylinder.
Figure 2-109
A concentrated magnetic field occurs from themagnet to the tip of the blade, attracting the mag-netic toner.
Once inside the concentrated magnetic field,the toner becomes virtually immobile because ofits strong bond to the blade, ensuring a thin, uni-form layer of toner on the cylinder.
An AC bias and a DC bias are simultaneouslyapplied to the developing cylinder and the blade(developing bias); as such, the positive compo-nent of the developing bias is greater than thenegative component.
Figure 2-110
During copying operation, toner is attracted tothe photosensitive drum or to the developingcylinder according to the strength of the magneticfield caused by the difference between the drumsurface potential and the developing cylinder sur-face potential (i.e., developing bias), thereby turn-ing the static image into a visible image.

G. Pre-Transfer Charging (step 5)
Figure 2-111
The toner on the surface of the drum is givenAC corona charges with a DC bias to increase itscharging, thereby improving transfer efficiencywhile at the same time facilitating paper separa-tion.
H. Transfer (step 6)
Figure 2-112
Positive corona charges are applied to theback of copy paper to attract the toner from thesurface of the drum to the copy paper.
To prevent transfer faults or soiling of the backof copy paper, the transfer guide is groundedthrough a varistor.
Reference:If the transfer guide was directly grounded,the charges that should be on the back ofpaper would escape, causing transferfaults; if cut off completely, on the otherhand, the transfer guide would be chargedand, ultimately, coated with toner to soil theback of copies.In high-humidity condition, partial transferfailure may occur. In some cases, ground-ing is wired with leading it through a varis-tor.

I. Separation (step 7)
Figure 2-113
Copy paper is charged to a positive potentialby the transfer charging assembly and is drawn tothe surface of the photosensitive drum by thework of static electricity. AC corona charges witha DC bias are applied to break the static bondbetween drum and paper, thereby separating thetwo.
J. Fixing (step 8)
Figure 2-114
After transfer, the copy paper is movedbetween two heating rollers so that the tonerimage will be fused into the fibers of the paper.
To prevent jams and toner offset, the upperroller is kept in contact at two points with a clean-ing belt impregnated with silicone oil; the take-upmechanism moves the area of contact, therebycleaning the belt while applying silicone oil to it.

K. Pre-Cleaning Exposure(step 9)
Figure 2-115
Pre-cleaning exposure is executed beforecleaning the drum, thereby removing the residualcharges from the surface of the drum to ensureuniform cleaning.
This step starts as soon as the pre-exposureLED turns on.
L. Drum Cleaning (step 10)
Figure 2-116
In preparation for the next copy, the surface ofthe drum is cleaned, ensuring the formation of acrisp image. (Cleaning blade scrapes off tonerremaining on the surface of the drum while themagnet roller collects it.)
The toner is then forwarded to the rear of thecopier for collection in the waste toner case.
Further, the friction against the magnetic brushof the magnet roller is used to deposit a thin coat-ing of toner on the surface of the drum, serving toensure the appropriate contact between the drumand the cleaning blade and proper cleaning oper-ation.

II. AUXILIARY PROCESSESA. Roller Electrode
Figure 2-201
A DC bias (negative component) is applied tothe roller electrode to collect any excess tonerthat did not move to the surface of the drum by theroller electrode, limiting soiling of the pre-transfercharging assembly and the transfer chargingassembly.
B. Separation Claw
Figure 2-202
If copy paper fails to separate from the photo-sensitive drum because of a pre-transfer chargingfault, separation charging fault, or feeding fault, itcould move into the cleaning assembly.
To prevent such a problem, a separation clawis located at the bottom of the cleaning assembly;the claw forces off copy paper from the drum,thereby keeping it from moving into the cleaningassembly.

C. Blank Exposure LampThe blank exposure lamp turns ON while the
drum is rotating except when an original is beingexposed (scanning moving forward), therebyremoving surface charges of the non-image areasto prevent adhesion of unwanted toner on the sur-face of the photosensitive drum.
As many LEDs of the blank exposure lamp ascorresponding to the varying non-image area tosuit the selected reproduction ratio are turned ONto prevent adhesion of unwanted toner on the sur-face of the drum.
D. Ozone FilterThe ozone filter is a catalytic filter used to
break down the ozone generated by chargingassemblies; the air exhaust fan assembly and thefeeding fan assembly are equipped with such a fil-ter to prevent the emission of ozone outside themachine. (See p. 3-150.)

In outline diagrams, represents mechanical drive paths, and indicates electricalsignal paths.
Signals in digital circuits are identified as 1 for High and 0 for Low. The voltage of signals, how-ever, depends on the circuit.
Nearly all operations of the product are controlled by a microprocessor; the internal workings ofthe processor are not relevant to the service persons work and, therefore, are left out of the discus-sions. By the same token, no repairs are prescribed for the PCBs at the users premises; for this rea-son, PCBs are discussed by means of block diagrams rather than circuit diagrams.
For the purpose of explanation, discussions are divided into the following: from sensors to mainPCB input ports; from main output ports to loads; and minor control circuits and functions.

B. Outline of Electrical CircuitryThe NP6085s major electrical mechanisms
are controlled by the microprocessors on its DCcontroller PCB
The two microprocessors are as follows andserve the functions given:1 Q158 (master)
Controls copying sequence. Controls high voltage. Controls fixing temperature. Controls scanner drive. Controls pick-up/feeding operations.
2 Q115 (slave) Controls the lens motor (X, Y). Controls the blank exposure LEDs. Controls the control panel. Controls analog signal input:
thermistor signalpotential sensor signalenvironment sensor signalmanual feed size signal
Controls the paper jogging guide drive motor.
The master (Q158) and slave (Q115) micro-processors exchange data through RAMs (Q166,Q188).
Communication with the RDF-D1, sorter, andC.F.F. is between the communication IC (IPC com-munication) on the controller PCB of the optionand the communication IC on the NP6085s DCcontroller.
Communication with the side tray does not usethe communication IC (IPC communication) but isin serial (100V model only).
As for the 208/220/240V model paper deck,communications are directly controlled by themicroprocessor on the DC controller PBC, sincethe drive loads are not many.
Figure 3-102 is a block diagram showing therelationship between the NP6085s major circuits.
